Crying can influence cortisol levels, but it doesn’t consistently reduce this stress hormone in every situation.
The Complex Relationship Between Crying and Cortisol
Cortisol is often called the “stress hormone” because it plays a key role in how our bodies respond to stress. When we face challenges or emotional turmoil, cortisol levels spike to help us cope by increasing energy availability and suppressing non-essential functions temporarily. But what happens when tears start flowing? Does crying release cortisol or help lower it?
The answer isn’t straightforward. Crying is a natural emotional response that can be triggered by sadness, frustration, joy, or even relief. Scientists have long studied whether shedding tears actually changes cortisol levels in the body. Some research shows that crying might help reduce cortisol after a stressful event, while other studies suggest the hormone could temporarily increase during crying episodes.
This complexity arises because crying involves multiple physiological systems—nervous, endocrine, and respiratory—and these systems interact differently depending on the context. For example, crying triggered by grief may affect cortisol differently than tears caused by happiness or irritation.
How Cortisol Functions in Stress and Emotion
Cortisol is produced by the adrenal glands as part of the hypothalamic-pituitary-adrenal (HPA) axis response to stress. Its main job is to prepare your body for “fight or flight” by:
- Increasing blood sugar for quick energy
- Suppressing immune functions temporarily
- Regulating metabolism of fats, proteins, and carbohydrates
- Influencing mood and cognitive function
When stress hits hard or lingers too long, cortisol levels can remain elevated—leading to fatigue, anxiety, weight gain, and other health issues. This makes understanding ways to manage cortisol crucial for mental and physical well-being.
Tears come into play as an emotional outlet that might signal the brain to dial down stress responses. But because crying itself can be linked to intense feelings like sadness or frustration—both triggers for cortisol release—the timing and type of crying matter.
Different Types of Tears: Reflexive vs Emotional
Not all tears are created equal. There are three types:
- Basal tears: Constantly produced to lubricate eyes.
- Reflex tears: Triggered by irritants like smoke or onions.
- Emotional tears: Released due to strong feelings such as sadness or joy.
Only emotional tears have been linked with changes in hormone levels like cortisol. Reflexive tears mainly serve protective purposes without significant hormonal shifts.
Scientific Studies on Crying and Cortisol Levels
Several studies have tried to pin down if crying reduces cortisol levels reliably. Here’s a quick look at some key research findings:
| Study | Method | Findings on Cortisol & Crying |
|---|---|---|
| Kraemer et al., 1984 | Monitored cortisol before & after watching a sad movie triggering tears. | Cortisol initially rose during crying but dropped below baseline afterward. |
| Suzuki et al., 2017 | Measured saliva cortisol in people who cried during emotional events. | Crying correlated with reduced subjective stress but no consistent drop in cortisol. |
| Pennebaker et al., 1990s | Analyzed biochemical composition of emotional tears. | Tears contained stress-related chemicals but unclear if they directly reduce hormones. |
These mixed results suggest that while crying might help people feel better emotionally, its direct impact on cortisol varies widely.
The Physiology Behind Crying’s Effect on Stress Hormones
When you cry emotionally, your body activates several systems simultaneously:
- Nervous system: The parasympathetic nervous system kicks in during prolonged crying episodes, promoting relaxation afterward.
- Endocrine system: Hormones like oxytocin and endorphins may be released along with or after tears, which can counteract stress hormones.
- Respiratory system: Deep breaths during sobbing help regulate oxygen intake and calm the mind.
This cocktail of responses could explain why many people feel calmer after a good cry even if their cortisol doesn’t immediately drop.
Interestingly, oxytocin—the so-called “love hormone”—released during social bonding or comforting moments often accompanies emotional crying. Oxytocin helps reduce anxiety and promote feelings of safety, indirectly influencing stress hormone regulation.
Crying as a Social Signal and Stress Modulator
Crying also serves as a nonverbal cue signaling distress to others. This social function may trigger supportive behaviors from friends or family that help lower overall stress levels.
When someone responds empathetically to your tears—offering comfort or just listening—your brain registers safety signals that can reduce HPA axis activation. The presence of social support is known to blunt cortisol spikes under stress.
So even if crying doesn’t directly flush out cortisol chemically from your system every time you cry, it often leads to environments where stress hormones decrease naturally through connection and reassurance.
Crying Without Tears: Emotional Release Still Counts
Sometimes people experience “silent” cries without actual tear production yet still report feeling lighter emotionally afterward. This suggests that physical tear release isn’t the only way crying influences mood or stress regulation.
The act of acknowledging pain or vulnerability alone activates brain regions responsible for calming fear responses and managing emotions effectively.
The Role of Individual Differences in Crying Responses
Not everyone cries the same way or reacts hormonally alike during emotional episodes:
- Cry frequency: Some people cry easily; others rarely do. Their bodies’ hormonal feedback loops differ accordingly.
- Cultural norms: Societal expectations shape how freely emotions are expressed which impacts physiological responses over time.
- Mental health status: Conditions like depression or anxiety alter baseline cortisol levels and reactions to emotional stimuli including crying.
- Sensitivity to stress: Those with heightened nervous system sensitivity may show stronger hormonal fluctuations when upset or tearful.
Because of this variability, generalizing about whether “crying releases cortisol” applies differently across individuals depending on genetics, upbringing, environment, and current health state.
The Science Behind Tear Composition: What’s in Emotional Tears?
Researchers have analyzed the biochemical makeup of different types of tears looking for clues about their function beyond eye lubrication:
| Tear Type | Main Components Found | Simplified Function/Effect |
|---|---|---|
| Basal Tears | Lipids, water, mucus enzymes (lysozyme) | Keeps eyes moist; protects against infection. |
| Reflex Tears (Irritants) | Tear proteins increase; flushes irritants out from eyes. | Cleanses eyes rapidly; no hormonal effect expected. |
| Emotional Tears (Stress) | Larger amounts of prolactin, adrenocorticotropic hormone (ACTH), leucine enkephalin (natural painkiller) | Might signal stress biochemically; potential mood modulation effects. |
The presence of ACTH—a precursor molecule stimulating adrenal glands—suggests emotional tears reflect internal hormonal changes rather than directly causing them. Leucine enkephalin acts similarly to endorphins providing natural pain relief which could partly explain why some feel better after crying.
The Aftermath: Does Crying Help Lower Cortisol Long-Term?
Even though immediate drops in cortisol post-cry aren’t guaranteed every time someone sheds tears under pressure, repeated emotional expression through crying might support healthier regulation over time by:
- Avoiding chronic suppression of emotions which keeps HPA axis hyperactive;
- Liberating internal tensions that otherwise accumulate;
- Nurturing social bonds through vulnerability;
- Paving pathways for relaxation via parasympathetic activation;
- Aiding psychological coping mechanisms that indirectly stabilize hormones;
- Avoiding maladaptive behaviors linked with bottled-up stress like anxiety attacks;
Thus crying could be part of an overall strategy for managing chronic stress rather than a one-time fix for high cortisol spikes.

Frequently Asked Questions
Does crying release cortisol during emotional stress?
Crying can cause a temporary increase in cortisol levels during intense emotional stress. This happens because crying is often triggered by strong feelings that activate the body’s stress response, including cortisol release.
Does crying release cortisol or help reduce it after stress?
Research shows mixed results: crying may help lower cortisol after a stressful event in some cases, while in others, cortisol levels remain elevated. The effect depends on the context and individual differences.
Does crying release cortisol differently depending on the type of tears?
Only emotional tears, triggered by feelings like sadness or joy, are linked to changes in cortisol. Reflex or basal tears do not significantly affect cortisol levels since they are not related to emotional stress.
Does crying release cortisol and affect mood regulation?
Crying interacts with cortisol and other physiological systems that influence mood. While it might temporarily raise cortisol, crying can also signal the brain to reduce stress responses and help regulate emotions over time.
Does crying release cortisol equally for all individuals?
The impact of crying on cortisol varies among individuals due to differences in emotional triggers, physiological responses, and context. Some people experience a decrease in cortisol after crying, while others may not.
Crying vs Other Stress-Relief Methods Impact on Cortisol Levels
Not all ways we manage stress influence hormones equally. Here’s how crying stacks up against other common methods:
| Stress-Relief Method | Cortisol Impact | Additional Benefits/Notes |
|---|---|---|
| Crying (Emotional) | Mixed results; temporary rise possible then drop; indirect reduction via social support & relaxation | Mood improvement; social bonding; natural expression |
| Meditation & Deep Breathing | Tends to lower baseline & acute spikes significantly | Pain management; improved focus; autonomic balance |
| Aerobic Exercise | Lowers chronic cortisol over weeks but acutely raises it during activity | Mood boosters; cardiovascular health; endorphin release |
| Social Support & Talking Therapy | Consistently lowers HPA axis activity when sustained over time | Improved resilience; cognitive reframing; empathy effects |
| Sleep Quality Improvement | Restores normal diurnal rhythm reducing excessive daytime cortisol elevations | Memory consolidation; immune function enhancement |
